Title: A process for the treatment of products having a basis of protein materials
IPC: C08L89/00
Filed: 1929-11-25
Abstract: 338,015. Soc. d'Applications et de Recherches Scientifiques et Industrielles (S.A.R.S.I.). Nov. 24, 1928, [Convention date]. Yarns &c., treating with liquids.-Protein substances such as gelatine, chondrin, ossein, albumen, casein, and gelose, which may be in the form of threads, acquire useful mechanical properties by treating with an alkali or alkaline earth metal thiosulphate in the presence of an acid or a salt which decomposes the thiosulphate and liberates sulphur in a colloidal or finely divided state within the mass. Threads employed in the textile industry are thereby given increased strength. A substance having a gelatine base is left in a bath of aluminium sulphate or an alum, such as potash or chrome alum, which may first be neutralized, until the swelling reaches the centre. It is then placed in a bath of sodium, potassium, or calcium thiosulphate, which penetrates the mass and is decomposed with liberation of sulphur. The treatments may be repeated until the entire mass is insoluble in hot water, and swells but little. A previous or subsequent treatment with substances producing insolubility or imperviousness such as formol, sodium borate, bichromates, picric or pyrogallic acids, tannin, or alums may be effected. A final bath containing glycerine, glycol, molasses, or a plasticizing agent imparts flexibility. Products resembling wool, hair and horn, of varying strength, imperviousness, and resistance to chemical action, are obtained by varying the concentrations, temperatures and duration of the baths, while treatment under pressure may sometimes be used.

Title: Finite memory filter
IPC: G06G7/625
Filed: 1974-08-19
Abstract: 1478385 Integrating circuits COULTER ELECTRONICS Inc 19 Aug 1974 [20 Aug 1978] 36440/74 Heading G4G Circuits having a Laplace impulse transfer function are realized using a design procedure which involves expanding the function as a continuous fraction and solving with the use of Bessel's coefficient equation a polynomial of convenient order N resulting from the fraction, the polynomial approximating the desired transfer function. The desired function is shown in Fig. 3 where the curve 70 is the desired response of the circuit to an impulse of unit amplitude. The circuit may be considered as an integrator which "forgets" the input signal after a finite time T. Curves 80, 82, 84 are responses of circuits according to the invention for N = 3, 5, 10 respectively. It is stated that N> 3 is impracticable and detailed examples of network synthesis for N=3 are given in the Specification. These are not susceptible to detailed abridgement. Briefly, the term e<SP>-sT</SP> (T = 1) is expanded in a continued fraction and approximated by the polynomial where the coefficient a K  is computed using Bessel's equation An expression for F(s) can be found which is more or less independent of T. Hence T can be re-inserted and T = 10 substituted, to obtain The realization of a circuit having this transfer function consists in providing a low-pass active filter 16, 22 which has a single-pole transfer function corresponding to the first factor of the expression. The second factor is realized as a so-called "biquadratic circuit", the synthesis of which is described in the Specification and in "State Variable Synthesis", Kerwin, IEEE Journal: Solid State Circuits, Vol. SC-2, pp. 87-92, Sept. 1967. The biquadratic circuit 28 comprises two summation circuits 30, 32 and two integrators 34, 36.

Title: Improvements in and relating to steam traps
IPC: F16T1/16
Filed: 1959-11-05
Abstract: 897,061. Steam traps. CLOUGH, G. F. G. Oct. 31, 1960 [Nov. 5, 1959], No. 37487/59. Class 64(2) In a steam trap comprising a body 1 having an inlet 2 and outlet 3 and surmounted by a cylinder 4 sealed by a cap 6 and containing a free piston 5, the piston carries a coaxial sleeve 13 having a bore 12 therethrough, the lower end of the sleeve forming a spigot 19 which projects into a recess formed in the underside of the piston and into the upper end of a sleeve 9 having a passage 8 therein communicating with the inlet 2. The upper end of the bore 12 is closed by a non-return ball valve 17 whilst its lower end opens into radial bores 25 in the spigot 19 leading into the recess in the piston. The spigot 19 bears on a ball 22 which controls the fluid flow into the steam trap. In operation, fluid pressure beneath the ball 22 lifts the piston and fluid passes into the compartment 11 thereabove through the bore 12 and valve 17 to exert a downward thrust on the piston. The fluid also passes upwardly through an annular space 21 between the spigot 19 and the rounded upper end 20 of the sleeve 9 and downwardly through a comparatively narrow annular space 23 between the sleeve 9 and piston skirt to a space 10 communicating through a passage 26 with the outlet 3. The relative dimensions of the piston diameter, the clearances of the passages 21, 23 and the ball controlled inlet passage 8 are so chosen that when liquid is flowing through the trap the piston remains lifted. When steam flows through the trap, however, its pressure drop between the inlet 8 and compartment 10 is more than when liquid is flowing and is such that the pressure above the piston forces the latter downwardly so that the spigot 19 closes the ball valve 22. A leakage of pressure then occurs past the piston until the pressure under the ball 22 again lifts the piston and the cycle is repeated. In a modification the piston 5 is replaced by a flexible -diaphragm or bellows.
